Canadians who work in pot industry could face significant risk crossing the border

Canadians who work in the marijuana industry — and those who invest in the booming pot sector — will face significant risks when crossing the U.S. border even after the drug becomes legal in Canada next month, according to detailed comments by a senior official overseeing U.S border operations.

A lifetime ban on entering the U.S. will apply to travellers who admit to using marijuana, employees in the marijuana industry, and investors in the marijuana sector, according to the official.
